Agriculture Single-Span/Multi-Span Plastic Film Greenhouse Hydroponics Grow System for Tomato/Lettuce/Cucumber/Flowers/Fruits

Hydroponics is the science of growing plants without the use of soil. It is also known as "Soilless culture". 
 
     In traditional agriculture where plants are grown in soil, nutrients and water exist randomly, and often plants need to expend a great deal of energy to grow long roots to search for water and nutrients. By expending this energy, plants do not grow as fast as they could. However in a hydroponic system, a plant doesn't have to expand any energy growing long roots in search of it. In addition, growing plants in hydroponics requires less water, less space, and pests and diseases are more easily controlled and prevented.
  Preparation before hydroponics
First prepare seeds, nutrient solution and a bucket of about 15L.Seeds can choose cabbage, lettuce, coriander, celery and other leafy vegetables.
Hydroponics steps:
1. Pour some seeds into the water for an hour.
2. Wrap the seeds in a wet towel, and put it in a dark and ventilated place.
3. Press the sponge into the water and let the air out, then sponge soaked for two hours.
4. After the seeds germinate, put the buds into the sponge(note:one bud in one sponge). Place the sponge in the basin and get the sun.
5. When the buds grow leaves, pour nutrient solution into the basin.The sponge needs to be kept moist.
6. When the seedling has three or four leaves, select the seedling of the root to penetrate the sponge,place it in the hole of hydroponics equipment and get the sun.
7. You can ask us for a video of the hydroponic course.
Design Principle
The unique inner plug design is used in the piping system. The inner plug is a PE material of food-grade. The design makes the
entire piping system S-flow. The drop in water increases the dissolved oxygen in the water.

The word hydroponics comes from Greek, which means "cooperation with water". It is a method of growing plants in nutrient-rich liquid instead of soil. This operation can be done outside warm weather or indoors all year round. It has many advantages, including: no weeding, rapid growth, high yield in narrow space, no small animals stealing crops, clean vegetables, easy harvest, consistent quality, no insects or diseases related to soil, etc.
